EDWIN O. PETERSON, OF ELGIN, NEBRASKA.

HOLLOW-WALL-MOLDING SYSTEM.

Specification of Letters Patent.

Application filed May 3, 1911. Serial No. 624,847.

To all whom it may concern Be it known that I, EDWIN O. PETERSON,

citizen of the'United States, residing at lilgin, in the county ofAntelope and State of Nebraska, have invented certain new and tionswhich are effectually locked together and braced the system includingmold sections which may be removed from the interior of the wall as thesaid wall is completed, leaving therein the tying devices above referredto.

\Vith this object in view the system includes inner and outer wallplates which are provided with overlapping edge portions, and means forholding said plates in proper relative positions. Mold sections arepositioned between the inner and outer face pl ates and may be removedfrom the wall as the same is completed. The system also includes tyingand reinforcing members, as will be hereinafter explained.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is a perspective view of a portion of awall formed by the useof the present system; Fig. 2 is a horizontal sectional view ofa wallsection showing the interior molds of the system in position therein;Fig. 3 is a sectional view of wall face plates used in the system; Fig.4 is a transverse sectional view of athrust screw used for holding thewall face plates in position; Fig. 5 is a perspective view of one of thewall face plates; Fig. 6 is a perspective view of the end portions ofbars used in the system; Fig. 6 is a perspectiveview of locking stripsused in the apparatus; Fig.

' 7 is a perspective view of a. interior wall face plate used in thesystem; Fig. 8 is a transverse sectional view of a section of wall.illustrating the manner in which a cornice is formed upon thesam'e; andFig. 9 is a perspective view of a modified form of wall tying memberwhich'may be used in the present system.

Corresponding and like parts are referred to m the following descriptionand 1nd1- cated in all the views of the accompanying draw'ngs by thesame reference characters.

The system includes outer wall face plates 1 which are recessed at theiredges, as at 2, the recess of one platebeing adapted to receive the endportion of an adjacent plate.

Patented July 2.3.1912;

These plates are placed edge upon edge and are held in position byhorizontal bars 3 which in turn are held in position by verti calstandards 1. Braces 5 are applied to the standards 4 and rods 6 connectthe lower portions of the said braces with the lower portions of thestandards 4. The upper and lower ends of the-standards at at the innerand outer sides of the wall are connected together by tie bolts 7 ofwhich but one'is shown and that in Fig. 1. The inner face plates 8 ofthe wall are of the same general strucforced into close contact with thesides of the plates 1 and 8 and hold the same in position.Semi-elliptical mold sections 12 are positioned between the plates 1 and8 at the time that the wall is being formed and the material is pouredbetween the plates'l and 8 and around the mold sections 19.. The moldsections 12 are provided with parallel. flange portions 18 and bars 14are positioned between the flanges 13 of the adjacent mold sections 12.These bars let are rectangular in transverse section and are provided attheir ends with reduced rectangular extremities 15. Looking strips 16are provided with rectangular openings 17" which snugly receive theextremities 15 of the bars 1% and hold the said bars in proper positionwith relation to "each other. The ends of the flanges 13 of the moldsections 12 which constitute one of the molds are spaced from the endsof the flanges of the adjacent mold. Tying devices are located betweenthe adjacent edge portions of the molds, andthe said devices consist ofparallel strips 17 and projectingrods 17 adapted to be embedded in theopposite sideportions of the wall. When the material is section of theWilii is completed the strips tciiui solidifies shout the rods 1'2" e {lthe inner the Wall tie:
